To fight hunger in Africa, a Penn State University program has helped design more affordable greenhouses and solar food dryers.
A conventional greenhouse costs about $2,500 in Kenya, Khanjan Mehta noted Dec. 4 at Bluffton University. But an alternative, expandable model—designed by a new Kenyan company and Penn State’s Humanitarian Engineering and Social Entrepreneurship program—is $550, said Mehta, the program’s director.
And solar dryers used for food preservation, which have cost as much as $5,000, can now be built by two people in two days for $200, he said.
